NEW HAVEN, Conn., July 31, 2023 /PRNewswire/ -- Biohaven Ltd. (NYSE: BHVN) (Biohaven or the Company), a global clinical-stage biopharmaceutical company focused on the discovery, development and commercialization of life-changing therapies to treat a broad range of rare and common diseases, today reported financial results for the second quarter ended June 30, 2023, and provided a review of recent accomplishments and anticipated upcoming milestones.

Vlad Coric, M.D., Chairman and Chief Executive Officer of Biohaven, commented, "In less than a year since our spin-off, the Biohaven team has driven strong and consistent progress across multiple drug development platforms. We were excited to recently report positive interim data from the ongoing EEG biomarker study of our lead Kv7 activator, BHV-7000.  As expected, BHV-7000 demonstrated CNS activity consistent with what has been reported in EEG studies with other Kv7 channel activators in development that are clinically effective in treating epilepsy and with other approved anti-seizure medications. Importantly, BHV-7000 demonstrates CNS target engagement but is not associated with the typical CNS adverse events associated with other ASMs, like somnolence and fatigue. We look forward to completing the higher dose groups in this EEG study and initiating Phase 2/3 studies with our once daily, extended-release oral formulation later this year."

Dr. Coric continued, "We also shared a number of equally exciting announcements across our broader pipeline this quarter. We successfully administered the first three doses in the SAD portion of our ongoing SAD/MAD study evaluating BHV-8000, an oral, brain-penetrant, dual TYK2/JAK1 inhibitor.  Potential therapeutic concentrations of BHV-8000 were achieved and BHV-8000 was well tolerated with only mild adverse events reported, reinforcing our plans to start a Phase 2 clinical trial with BHV-8000 in Parkinson's disease and potentially other neuroinflammatory diseases in 2024. In addition, we have advanced IND enabling preclinical studies and remain on track to submit an IND with our IgG degrader, BHV-1300, later this year. We also anticipate submitting an IND with our IgA degrader in 2024 as we continue to advance multiple clinical degrader candidates across a wide range of indications. We also shared key updates for our taldefgrobep alfa program (an anti-myostatin) with enrollment completion in our pivotal study in SMA and a planned Phase 2 trial initiation in obesity."

"Finally, I want to reaffirm Biohaven's commitment to the SCA3 patient community in spite of the recent disappointing regulatory decision by the FDA not to review our submitted NDA. Given the seriousness of SCA3 and consistent treatment benefits observed across multiple prespecified outcome measures, including an 80% delay in disease progression over the one-year study period with substantial risk reduction in falls, we believe that full consideration of all available data is warranted for this ultra-rare disease. Biohaven has built its foundation around our patient mission and we plan to continue to work with regulatory agencies to try to advance troriluzole for individuals suffering from SCA3."

Second Quarter 2023 and Recent Business Highlights

• Announced positive interim data from EEG biomarker study with BHV-7000 - In July 2023, the Company provided a preliminary data update from the ongoing electroencephalogram (EEG) biomarker study for the Kv7 Channel Activator platform. Preliminary Phase 1 data confirmed evidence of target engagement in the central nervous system for subjects with projected therapeutic concentrations of BHV-7000 (based on the EC50 from preclinical models), measured by changes from baseline in EEG spectral power that occurred after dosing. These pharmacodynamic (PD) effects were similar to those reported in the literature for anti-seizure medicines (ASMs), including Kv7 activators in development that are clinically effective in treating epilepsy. BHV-7000's PD effects were also differentiated from those reported for other Kv7 activators including, specifically, the absence of increases in EEG spectral power in frequency bands associated with drowsiness and somnolence. Results from the low-dose group validate the preclinical hypothesis, confirm the Phase 1 SAD/MAD clinical data, and provide strong support for Biohaven's plans to initiate pivotal studies with BHV-7000 in focal epilepsy and bipolar disorder in the second half of 2023. The preliminary data highlight BHV-7000's differentiation and potentially favorable clinical profile compared to other ASMs, and the Company expects to present the complete EEG results by the end of the year. Additionally, new pharmacokinetic data from multiple clinical formulations being studied has now confirmed a once daily extended-release oral formulation that will be used in the Phase 2/3 clinical programs.
  
  
• Successfully dosed three cohorts with single ascending doses of oral, brain penetrant, dual TYK2/JAK1 agent, BHV-8000 - In July 2023, the Company announced that it successfully dosed three cohorts in the SAD portion of an ongoing SAD/MAD Phase 1 study evaluating brain penetrant TYK2/JAK1 agent, BHV-8000 in healthy volunteers. The ongoing Phase 1 study is designed to evaluate the safety, tolerability, pharmacokinetics (PK) and PD of single and multiple ascending doses of BHV-8000 in healthy volunteers. Based on the preliminary data available, projected therapeutic concentrations of BHV-8000 were achieved, and BHV-8000 was well tolerated with only mild adverse events reported. These data provide support for further development of BHV-8000, and the Company anticipates beginning a Phase 2 clinical trial with BHV-8000 in Parkinson's disease and potentially other neuroinflammatory diseases in 2024. The Company had previously reported initiation of dosing with BHV-8000 in the Phase 1 study at Biohaven's R&D Day in May 2023.
  
  
• Reported on continued progress observed with Biohaven's first-in-class bispecific IgG degrader, BHV-1300, as compound advances to IND filing in 2H2023 - In July 2023, the Company shared an update on  BHV-1300's highly competitive safety, manufacturable and PD profile. The Company is assembling a pipeline of partially de-risked, follow-on IgG degraders as well as antigen-specific degraders providing both optionality and a sustainable output of drug candidates for several years. An IND application for BHV-1300 is on track for submission in 2023 and an IND application for Biohaven's IgA degrader on track for submission in 2024
  
  
• Type A meeting planned to comprehensively address FDA's concerns in connection with Troriluzole program in SCA3 - In July 2023, the Company announced that the FDA informed Biohaven it would not review the recently submitted New Drug Application (NDA) for troriluzole for the treatment of spinocerebellar ataxia type 3 (SCA3), an ultra-rare, genetically-defined, neurodegenerative disease associated with progressive disability, frequent falls, loss of ambulation, speech and swallowing impairment, and premature death that is the most common SCA genotype worldwide. The FDA informed Biohaven it would not review the application given that the study's primary endpoint was not met and thus, would not permit a substantive review. Biohaven is committed to working closely with the FDA to bring troriluzole to people with SCA3 as quickly as possible given no therapy is currently approved for this ultra-rare genetic disorder. Biohaven plans to request a Type A meeting to comprehensively address FDA's concerns cited in the refusal to file letter.
  
  
• EMA orphan drug designation granted for taldefgrobep alfa for the treatment of SMA: - In July 2023, the Company announced that taldefgrobep alfa received orphan drug designation (ODD) from the European Commission for taldefgrobep for the treatment of SMA. Taldefgrobep previously received Fast-Track and ODD from the FDA. At Biohaven's R&D Day, the Company announced plans to complete randomization of approximately 180 patients in global SMA trial.

Capital Position:

Cash, cash equivalents and marketable securities as of June 30, 2023 was $349.0 million, including $13.9 million of restricted cash, and excluding $40.4 million of cash payable to Biohaven Pharmaceutical Holding Company Ltd. (the Former Parent), compared to $467.9 million, including $2.5 million of restricted cash, and excluding $35.2 million of cash payable to the Former Parent, as of December 31, 2022¹.

Second Quarter 2023 Financial Highlights:

Research and Development (R&D) Expenses: R&D expenses, including non-cash share-based compensation costs, were $79.5 million for the three months ended June 30, 2023, compared to $177.1 million for the three months ended June 30, 2022. Non-cash share-based compensation expense was $2.5 million for the three months ended June 30, 2023, a decrease of $10.3 million as compared to the same period in 2022. Non-cash share-based compensation expense was higher in the second quarter of 2022 primarily because expense allocated from the Former Parent equity plan, prior to the spin-off, was based on equity awards with higher grant date fair values.

General and Administrative (G&A) Expenses: General and administrative expenses were $14.5 million for the three months ended June 30, 2023, compared to $20.0 million for the three months ended June 30, 2022. The decrease of $5.5 million was primarily due to decreased non-cash share-based compensation costs. Non-cash share-based compensation expense was $2.2 million for the three months ended June 30, 2023, a decrease of $5.8 million as compared to the same period in 2022. Non-cash share-based compensation expense was higher in the second quarter of 2022 primarily because expense allocated from the Former Parent equity plan, prior to the spin-off, was based on equity awards with higher grant date fair values.

Other Income (Expense), Net: Other income (expense), net was a net income of $5.8 million for the three months ended June 30, 2023, compared to net expense of $0.1 million for the three months ended June 30, 2022. The increase of $5.9 million was primarily due to an increase in net investment income and an increase of $1.7 million in other income related to our transition services provided to the Former Parent, which is largely non-recurring.

Net Loss: Biohaven reported a net loss for the three months ended June 30, 2023, of $90.3 million, or $1.32 per share, compared to $203.3 million, or $5.16 per share, for the same period in 2022. Non-GAAP adjusted net loss for the three months ended June 30, 2023 was $85.7 million, or $1.25 per share, compared to $182.5 million, or $4.63 per share for the same period in 2022. These non-GAAP adjusted net loss and non-GAAP adjusted net loss per share measures, more fully described below under "Non-GAAP Financial Measures," exclude non-cash share-based compensation charges. A reconciliation of the GAAP financial results to non-GAAP financial results is included in the tables below. For periods prior to Biohaven's spin-off from the Former Parent on October 3, 2022 (the "Spin-Off"), net loss per share and non-GAAP adjusted net loss per share were calculated based on the 39,375,944 common shares of Biohaven distributed to the Former Parent shareholders at the time of the distribution, including common shares issued in connection with the Former Parent share options that were settled on October 3, 2022 and common shares issued in connection with the Former Parent restricted share units that vested on October 3, 2022.  The same number of shares is being utilized for the calculation of basic and diluted earnings per share for all periods presented prior to the Spin-Off.

Non-GAAP Financial Measures
This press release includes financial results prepared in accordance with accounting principles generally accepted in the United States (GAAP), and also certain non-GAAP financial measures. In particular, Biohaven has provided non-GAAP adjusted net loss and adjusted net loss per share, which are adjusted to exclude non-cash share-based compensation, which is substantially dependent on changes in the market price of common shares. Non-GAAP financial measures are not an alternative for financial measures prepared in accordance with GAAP. However, Biohaven believes the presentation of non-GAAP adjusted net loss and adjusted net loss per share, when viewed in conjunction with GAAP results, provides investors with a more meaningful understanding of ongoing operating performance and can assist investors in comparing Biohaven's performance between periods.

In addition, these non-GAAP financial measures are among those indicators Biohaven uses as a basis for evaluating performance, and planning and forecasting future periods. These non-GAAP financial measures are not intended to be considered in isolation or as a substitute for GAAP financial measures. A reconciliation between these non-GAAP measures and the most directly comparable GAAP measures is provided later in this news release.
